Item in-stock

The Mineral Plus+ Calcite Cartridge System adds back in the essential minerals (calcium & magnesium) to your drinking and cooking water which are removed from RO systems and Ultra filtration systems.

What does the Calcite Post Cartridge do? back to top
When installed after an RO system, this cartridge adds beneficial and needed calcium and magnesium back into the water. RO systems remove nearly 99% of all minerals and anything else from the water. Adding this after your RO will help keep your water balanced and full of beneficial minerals.

Great product. Our city water was terrible and we always bought bottled water to drink. Now we can drink the water right from the tap. It has only been a little over a month but I would recommend Pelican water system to anyone.

filters and softener

The product was delivered on time and installation was easy. Instructions were plain and simple to understand. The filters and softener have been in for only one week and have made a difference in the quality of water.

Great water

We are extremely pleased with our system. Our son had eczema and after installing our system, it has completely gone away and our water feels even nicer on our skin. Would recommend this product to also make sure you have safe drinking water.

Top notch products from a top notch company

I originally purchased a Pelican water system for my house 7 years ago. Pelican Water was the only company to give me an honest assessment as to what I needed, it included the Iron/Manganese filter along with the PC600. Since then I have enjoyed life with clean and safe water. Throughout the years I've replaced parts of the system due to wear and tear, most recently the head on my Iron filter died from a power surge during a storm. Pelican (Trevor from support) pointed me in the best way to get the system running, replacing the head instead of selling me an entire new filter tank and head. Pelican support is GREAT to work with, always having the answers and making sure it is what is best for the customer. Thank you for all of your great products and services!

Getting it installed in my complicated basement of my old house required the help of a plumber but it was worth it. We used to have to use vinegar in a jar in the dishwasher to keep a white coating from covering the dishes. Now the dishes come out spotless. I feel there will be so much less buildup in the dishwasher as well as the washing machine. Taste of water without chlorine and whatever white good was in there makes for perfect drinking water. Experienced no decrease of water pressure. Don't have to worry about boil bands when something goes wrong with city water. Sometimes we don't find out about it right away. No more buildup at the faucets and toilet tank. Excellent product. Reviewed every similar product out there and was glad I chose Pelican. Customer service is also a joy to work with as I was trying to decide which model to buy.

fast & helpful

I was tempted to buy the cheaper version of this bulb on Amazon but I'm glad I didn't as many of the reviews made it clear that "you get what you pay for". I also liked the videos on youtube that shows you how to do the intallation step by step. Fast delivery. Pelican does great1
